Really like this app. It does have the ability to retroactively record sleep, as long as you put in your sleep start and end time within 4 days. Wish I could just set it up with the same start and end time every day and have it automatically track sleep. Also it would be cool if it could wake you by vibrating your bed. 5/20/17: update. Find myself not really using the app. It's too tedious to enter stop and start times, even after the fact. Wish it was automatic or it just used my preset times. Also, not sure if the data is accurate or made up.
This app works reasonably well for one person. My husband and I each have the app on our smartphones. We each have our sleep tracker accounts linked to our Amazon accounts so that we can control it from Alexa. However Alexa seems to only be able to start one recording not both. If we try to start the 2nd recording it says a recording is already in progress even though we switched account. Also the app on both our phones has a symbol for a remote however the app remote doesn't control the bed from either phone. It would be nice if we could control the bed from Alexa and not even need the control.
The only improvement that I can think of is if the back could be heated for those of us that get sore backs.
Good app. If used properly. Just learning what it can truly do
Very unreliable as noted by other reviewers. The sleep tracker was one of the features that convinced me to buy this expensive adjustable base, but it has numerous flaws. For example if I have the head of the bed elevated at all the sensors won't record. Well that's why I purchased an adjustable base, to help with my post nasal drip, so I use about a 10% elevation. If I go to sleep after midnight then ( ie 12:30am) on Saturdau then go back to bed at 11 Pm that Saturday, no recording. Very disappointing.
Doesn't seem to be accurate. I wake up and it says that I'm asleep during the time I'm up. The notes that it gives you are very broad and not individualized. Making the payment is more of a hassle than its worth.
